FIELD OF THE PRESENT INVENTION

The present invention relates generally status indicators for instruments, and more specifically relates to an illuminated handle on portable instruments that is configured to illuminate in order to indicate one or more status states.

BACKGROUND OF THE PRESENT INVENTION

A wide assortment of data collection instruments are known on the market today, many of which are configured for use by an individual holding the instrument in his or her hand. Such portable instruments are often configured to gather environmental data via one or more onboard environmental sensors.

Most indicators of conventional instruments are known to be disposed on the front of the unit, and are often present in the form of LEDs, screens, etc. Mechanisms such as these are not visible if the user walks around the instrument, or away from the instrument.

Conventionally, in order to provide such status visibility to the user of the instrument, a light stick (namely, a pole equipped with an illuminated status indicator) is often used in conjunction with a measuring instrument, such as a particle counter, to allow the status of the particle counter to be visible throughout the room. As with particle counters in a cleanroom, keeping the instrument easy to wipe down means eliminated extraneous projections from the instrument enclosure. Therefore, such a device would need to be equipped with indicators that are flush or disposed inside of the body of the instrument enclosure, such as within the handle of the instrument.

Thus, there is a need for an illuminated handle for portable data collection instruments that is configured to interface with the data collection process of the instrument itself, and display a color via at least one light embedded within the handle that corresponds to the status of the data collection instrument. Such a device is preferably integrated within the instrument, however some embodiments of the present invention may be configured to augment or replace an existing handle on a data collection instrument to afford the instrument the features of the present invention. Also by combining a “light stick” with a “handle” of the measuring instrument via the present invention, extraneous projection of light is eliminated, and the cost of use is reduced.

SUMMARY OF THE PRESENT INVENTION

The present invention relates to a new apparatus configured to provide a visible indication of the status of an instrument at a distance and from any direction. The apparatus of the present invention amounts to a visual indicator system which is preferably integrated within or attached to a handle of the instrument. At least one light is disposed within the handle, and is in communication with the sensor(s) of the instrument via internal wiring.

The lights are configured to illuminate, displaying a specific color and/or flashing sequence to indicate one or more statuses of the instrument. The placement of the at least one light within the handle of the instrument ensures that the status of the instrument is constantly visible to the user of the instrument, without the need to continually view a status screen, gauge, or monitor of the instrument in order to determine the present status of the instrument/sensors in real time. The illumination from the at least one light disposed in the handle of the instrument can preferably be seen from a distance, such that the user may easily know the status of the instrument, including ranged readings obtained by sensors of the instrument, even when he or she is no longer holding the instrument.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention is an apparatus configured to indicate the status of an instrument via colored light. More specifically, the present invention is a new form of data collection instrument configured to enable the user to determine the status of the instrument from any angle, and from a distance within a room. The present invention is a data collection instrument (10) which is equipped with a handle (20). The entirety of the handle (20) contains at least one light, referenced as lights (30), which are preferably embedded within the handle (20) of the present invention, such that they do not protrude out from the handle (20). As such, the blubs of the lights (30) are housed within or are flush with the enclosure of the instrument. The lights (30) are in communication with a light controller (40), which is housed within the instrument. The light controller (40) is configured to alter the color of the light emitted from the lights (30) according to the present status of the data collection instrument (10). The lights (30) are preferably oriented to cast light away from the handle (20) of the instrument (10), such that the user may detect the status of the instrument (10) from any angle or direction without having to physically approach the instrument (10) to determine its status.

The use of multiple colors by the present invention, emitted by the lights (30) within the handle (20), facilitates the remote viewing of the status of the instrument (10). For example, the color ‘red’ may indicate that an alarm is present during the measurement by the instrument (10), indicating an error of the sensor(s). Conversely, the lights (30) illuminating the color ‘blue’ may indicate that the sampling data is in progress by the instrument (10). The color ‘Yellow’ may be configured to indicate that the instrument (10) requires service and/or calibration. Similarly, the color ‘green’ emitted from the lights (30) may indicate that the instrument (10) is calibrated and ready for use. It is envisioned that lights assigned to varying statuses may vary according to the instrument (10) employing the system of the present invention.

It should be noted that FIG. 1 and FIG.2 depict example embodiments of the present invention, and the present invention is not limited to handle designs such as these. As such, the present invention may be incorporated on any format of handle used on data collection instrument, especially those used for gathering environmental data.

Preferred embodiments of the present invention are preferably equipped with multiple iterations of the lights (30) of the present invention. Such embodiments are preferably configured to illuminate the entirety of the handle (20) of the instrument with a uniform illumination. However, some embodiments of the present invention may be configured for integration within smaller instruments, and may only be equipped with a minimum singular light (30) of the present invention. In such cases, the light (30) is preferably still oriented such that it may illuminate a majority of the handle (20) during use.

In some alternate embodiments of the present invention, the lights (30) are disposed at the end(s) of the handle (20), such that the only the end(s) of the handle (20) are illuminated during use, such that the light remains visible while being carried by the user. Preferably, the entirety of the handle is illuminated by the lights (30), however some components of the handle may interfere with the uniform distribution of illumination within the handle. While the present invention is preferably integrated within the instrument, some embodiments of the present invention may be configured as a modular, add-on accessory to existing portable sensor instruments. In such cases, the present invention features a clip-on handle light and wiring, which enables the user to affix the clip-on handle light to the existing handle of the instrument, and connect it to the sensor of the instrument such that the lights (30) can indicate the status of the instrument during use.

The process of use of the present invention, as depicted in FIG. 2, is preferably as follows:

-   1. A user has a need to obtain measurement data via a portable     environmental sensor instrument. (100) -   2. The user obtains the portable environmental sensor instrument     applicable to obtain the desired data; the instrument is equipped     with the present invention. (110) -   3. The user activates the instrument. (120) -   4. Lights disposed within the handle of the instrument illuminate to     inform the user of an initial status of the instrument. (130) -   5. The lights illuminate a first color, indicating that the sensors     of the instrument must be calibrated and/or serviced. (140) -   6. The user calibrating and/or servicing the instrument. (150) -   7. The lights within the handle of the instrument displaying a     second color, the second color indicating a ‘ready for use’ status.     (160) -   8. The user taking a reading with the instrument. (170) -   9. The lights illuminating a third color, indicating to the user the     status of ‘reading in progress.’ (180) -   10. The user observing the lights to obtain the status. (190) -   11. The lights illuminating a fourth color, indicating to the user     the status of ‘reading complete.’ (200) -   12. The user obtaining and recording the needed measurement data.     (210)
